I had an idea to improve the GMAT Club tests
. Its more of an organization tool than test content.
If the testmakers were to make question categories (similar to the hardest questions category) for every type of question included in the 25 tests. Then if someone wanted to just practice number properties for example, they could click on the link, and they may have 100 questions or so on number properties that they can work through. I think a lot of people are just going through the problems at this point to better understand the formulas/content, etc. I think they are great as is, but I think this would allow people to focus on their weaknesses a little better. I find that with a lot of questions in any given test, I have the concepts down really well, and then I hit a few tough ones. This would maximize people's time in studying. Sorry if the paragraph is hard to follow...I am tired at this point of the evening.
